Definitions
- the present invention relates to a crimping device according to the preamble of the independent claim.
- Crimping devices are widely used in industry to seal containers. For example, in production lines for the production of certain pharmaceutical products, a container having a flange is first filled with the product, e.g. a liquid, and then a stopper (septum) is inserted into the opening of the container. Finally, the container is sealed by a cap, e.g. made of aluminium, through crimping the cap around the flange of the container. The crimping is performed by a crimping device comprising a circular disc, which deforms the cap beneath the flange of the container, while the container is rotated around its axis.
- a crimping device comprising a circular disc, which deforms the cap beneath the flange of the container, while the container is rotated around its axis.
- a known crimping device has a circular disc made of hardened steel exhibiting a high durability.
- the circular disc is arranged so as to only contact (deform) the cap to be crimped around the flange.
- the circular disc made of hardened steel strikes against the container anyway. Since the containers are often glass vials, such striking of the circular disc with the glass vials may result in scratches being formed on the glass vials. These scratches may weaken or even damage the glass vials, sometimes even make the glass vials break. Alternatively, cracks or fissures in the glass vial may occur which may result in that the content of the vials may leak through these cracks or fissures. Any of these occurrences could cause contamination of the content of the vials.
- the disc comprises first and second disc members abutting against one another, with the second disc member extending outwardly beyond the first disc member and having a hardness smaller than that of the container. Therefore, if at all, then only the second disc member can strike against the container during crimping.
- the second disc member effectively prevents the first disc member from striking against the container, while crimping of the cap around the flange of the container is reliably performed.
- the first disc member can still be made of hardened steel, like in the known crimping device, and can therefore exhibit high durability while at the same time damages to the container (e.g. glass vial) are prevented.
- the first and second disc members are circular disc members having a common rotational axis, with the diameter of the second disc member being greater than the diameter of the first disc member.
- the means for producing a relative movement between the disc and the flange of the container are designed such that the container holding the cap to be crimped is rotated around its rotational axis while the disc is in contact with the cap. Crimping is effected all around the container and the container gets sealed all around its flange. This also constitutes a simple way of implementing the relative movements in a production line from a constructional point of view.
- the first disc member comprises a pin and the second disc member comprises a hole.
- the pin of the first disc member is press-fitted into the hole of the second disc member.
- a further embodiment of the crimping device comprises screws fixing the second disc member to the first disc member. These screws enable the first and second disc members to be mounted together and to make sure that the second disc member extends radially outwardly beyond the first disc member all around the first disc member and thus avoiding damage to the container. Replacement of any of the disc members can also be performed in a simple way, by unscrewing the second disc member from the first disc member.
- the second disc member extends radially outwardly beyond the first disc member by 0.1 mm to 0.4 mm, in particular by about 0.2 mm. This distance is suitable to make sure that the first disc member does not strike against the container.
- the second disc member has a thickness in the range of 1 mm to 10 mm, in particular of about 2 mm.
- the specified thickness of the second disc member is suitable to prevent deformation of the second disc member caused by striking against the container.
- the second disc member is made of ERTYLYTE ® PET. This material is solid and durable and does not damage the (glass) container.
- Fig. 1 shows a prior art crimping device P1.
- Crimping device P1 comprises a disc P10 made of hardened steel exhibiting a high durability.
- Disc P10 is shown during crimping a cap 21 around a flange 20 of a container 2.
- Container 2 is positioned next to disc P10, with disc P10 being arranged beneath flange 20.
- Container 2 is then rotated around its axis and disc P10 is crimping cap 21 inwardly against flange 20 of container 2, thus sealing container 2.
- disc P10 is arranged so as to only contact cap 21. However, it may occur that during the process of crimping that the disc P10 strikes against container 2. Since the containers 2 are often glass vials such striking of disc P10 against the glass vials may result in scratches being formed on the glass vials. These scratches may weaken or even damage the glass vials, sometimes even make the glass vials break.
- Fig. 2 shows an embodiment of a crimping device 1 according to the invention.
- Crimping device 1 comprises a disc 10.
- Disc 10 comprises a first disc member 100 and a second disc member 101.
- Second disc member 101 abuts against first disc member 100 and extends outwardly beyond first disc member 100.
- a container 2 with a flange 20 and a cap 21, e.g. made of aluminium, covering the opening of container 2.
- Cap 21 is being crimped around flange 20.
- First disc member 100 and second disc member 101 are circular disc members with a common rotational axis 11, with the diameter of second disc member 101 being greater than the diameter of first disc member 100.
- Second disc member 101 extends radially outwardly beyond first disc member 100 by 0.1 mm to 0.4 mm, in particular by about 0.2 mm.
- Second disc member 101 has a thickness in the range of 1 mm to 10 mm, in particular of about 2 mm, and is made of ERTYLYTE ® PET, for example, which can be obtained from Angst+Pfister AG, Switzerland.
- Crimping device 1 also comprises means for producing a relative movement between the disc 10 and the flange 20 of the container 2 (see arrow 4 in Fig. 4 ), so that container 2 holding cap 21 is rotated around its rotational axis, while first disc member 100 is in contact with cap 21.
- Container 2 is rotated all around its rotational axis to crimp cap 21 inwardly against flange 20 by deforming cap 21.
- Disc 10 is arranged so as to only contact (deform) cap 21. However, it may occur that during the process of crimping, disc 10 strikes against container 2 anyway. In such case, only second disc member 101 which extends radially outwardly beyond the first disc member 100, strikes against container 2. First disc member 100 does not strike against container 2 at all. As second disc member 101 has a hardness smaller than that of container 2, no damage to container 2 occurs when second disc member 101 strikes against container 2.
- Crimping device 1 may comprise screws 12 fixing second disc member 101 to first disc member 100, or alternatively first disc member 100 comprises a pin 13 and second disc member 101 comprises a hole, wherein pin 13 of first disc member 100 is press-fitted into the hole of second disc member 101.
- Fig. 3 shows an embodiment of a container 2 with a flange 20 and a cap 21 before crimping. Also shown is a stopper (septum) 23 and a protecticve plastic button 22 forming a part of the cap.
- stopper 23 is inserted in the opening of container 2 so as to close container 2.
- cap 21 and protective button 22 are arranged over stopper 23 and flange 20 of the container 2.
- Cap 21 is now ready for crimping.
- Protective button 22 prevents the stopper 23 from damage and indicates that the container has not been opened yet.
- Fig. 4 shows a cross-section of container 2 of Fig. 3 and crimping device 1 of Fig. 2 .
- Crimping device 1 comprises disc 10 with first disc member 100 and second disc member 101.
- Container 2 is shown with its flange 20, cap 21, protective button 22 and stopper (septum) 23.
- a retainer 3 holding container 2 in place during crimping.
- Fig. 4 shows on the right hand side container 2 with cap 21 being crimped, while on the left hand side cap 21 is not yet crimped.
